I should say so.  My Mac II has the IIx motherboard in it, and I don't mean
any kind of upgrade.  It just happens that Apple only makes one '6 slot'
motherboard, and it is used for the IIx and the II.  The only differences are
that the II has ROM DIP sockets soldered on, and the IIx has ROM SIMM sockets,
and that the IIx has the solder holes where the PMMU socket should be filled
in through all four layers (a lot of pass-throughs in a pattern).  In short,
if the IIx takes 4 Meg SIMMS, then the II will too.  And although Apple may
be jerks, they are always good about bug-fixes.  If you have the old 24-bit
ROM and get a RAM card, they will upgrade your motherboard free.  Expect the
same thing for 4 Meg SIMMS.
