You can do this, sort of.

Make sure the Long Exposure Noise Reduction feature is turned on and take a long exposure. Once done, the shutter will close for same duration as the exposure so that the camera can make a dark frame.

Not a good idea.

First of all, you should never change a lens with the camera turned on.

I did it several times by mistake. Nothing happened or maybe I did not realize. For sure it's not a good thing to do but what exactly is supposed to happen if you do it?
