Yes, definitely.  I ran this and got a big patch:

  sed -i 's/INTEGERP/FIXNUMP/g' *.[ch]
  sed -i 's/make_number/make_fixnum/g' *.[ch]
  sed -i 's/CHECK_NUMBER/CHECK_FIXNUM/g' *.[ch]

I wasn't sure if I should try to rename NUMBERP or NATNUMP.
On the one hand they are really checking only for fixnums.
On the other hand, the logical names seem like they'd be unwieldy.

Also I was not sure what to do with calls like:

#define lisp_h_CHECK_FIXNUM(x) CHECK_TYPE (FIXNUMP (x), Qintegerp, x)

Here it is using 'integerp, but that will be a bit false.



Also I found the bug with arith_driver and now the branch can bootstrap
again.
