Yes, you can do that, but I don't know why you would want to. It's safer to
change them with the power on, as long as you don't poke your fingers in the
back where the AC line voltage is.

The memory chips only require 2V to retain their contents (and probably do
so well below that in real life), so there's plenty of room for the battery
to run down part way before you lose your memory.
