Maybe. From a safety standpoint, sure. Whether you can or not depends on if the seated bullet will still enter the neck sizing portion of the die. I doubt it will.

Putting extreme pressure on a loaded round in a sealed chamber, what could possibly go wrong? 
I guess it depends on how many you have to do, and how much work it would be to pull them.
Lengths and angles of the shoulders are the same, so it should work alright.
Let us know if your wedding tackle falls off.

If you can get the neck of a loaded round into your FL die, without a great deal of force, your FL die is made to the wrong neck dimensions. However, a Redding body die will bump back the shoulder of a loaded round just fine, since it doesn't size the neck at all.
that's why I want to use a 30/06 die to bump the shoulders on a .270. I have the die already, but I haven't picked up my puller yet. I have 50 to do. not sure if they all need it, but some were tight last time I loaded them. I forgot and just necked sized these.

What can happen when loading a compressed load? I never read any warning about that.
Nothing will happen. At least that has been the results of compressing loads for 652,804,726 times, without incident.
Same as bumping back shoulders---nothing happens, except the shoulder gets bumped back a bit.
My reloading experience is limited to say the least. Could someone please enlighten me. I've never heard of this. Why would this be done ???
There's a lot of guys doing it with body dies. I've done it myself on occasion, even though logic tells me that there isn't enough upside to compensate for the potential downside no matter how good the odds are.
Say you partially sized your cases (but not enough) or neck sized your cases one time too many and you have a pile of loaded ammo that chambers with difficulty or not at all. Or maybe you loaded ammo for one rifle and it won't chamber in another. You could size the loaded ammo a bit and avoid pulling them all down, resizing and loading again. It will work, but whether its a good idea is something that an individual will have to decide for himself. You'll never get Redding to recommend the practice, although I know there's a pile of guys doing it.
When you say difficulty in chambering, do you mean tight on the turn down or no turn down possible? I have made a few assumptions over the years and ended up with tight cases, if I can bring the cartridge to full lock up even with a lot of force I usually just do this and fire them (after lubing the locking lugs adequately). If it is an absolute no-go then I have been known to bump loaded ammo with the next size up die. Not a great solution but I've never had an incident. You may not get close enough to the shoulder junction with the 06 die though and find that although you can move most of the shoulder back that bump at the neck/shoulder junction still won't allow you to chamber the case. Have you any 7mm dies at all, that you could bump the neck junction back with? Shoulder angle doesn't matter at this point, you just need to iron out that little bump at the junction. Also make sure you don't over do it and create excess headspace, I usually do this a little at a time until I can close the bolt but still feel significant resistance so I know I haven't over done it. Usually we're only talking 3-5 thou is all you need to allow the cartridge to chamber, if it has been fired in this rifle before.
