Yes but RAM is on CPU board = full speed. A500 Slow RAM is shared with Agnus bus. 0xc00000 does not always mean slow ram, even original A2000 (not "B2000") had real fast at 0xc00000.

CPU boards with onboard RAM: RAM can be mapped anywhere, even on top of IO or ROM regions. (which of course would not make any sense..)
