Yes, the light will just unscrew out of the forend. But by taking the light out you're going to risk getting contamination (dirt etc) on the contacts. I have seen guys put plastic plugs in there though.
As for wear and tear though, I don't think it's all that necessary. I've had the same 6p for 8 years and I've never tried to be "nice" to it. It's been a pocket light, mounted on my C7 barrel and mounted in a surefire forend on my 670 when I was in the military. Since I retired it's been in a squeeze mount an mounted on my M500 rail. It's seen constant hard military and civii use the whole time I have had it and I've never even had to change the bulb..
So don't worry about taking it easy with it, mount it and enjoy it.
