AFAIK A1200 trapdoor slot has pins for full 32-bit address space but only 24 are connected in both Amiga and accelerator side. (Cheaper boards, cheaper memory controller)

24-bit CPU address space limit in A4000 would not allow access to A4000 mainboard fast ram or to any Z3 boards.

It probably would "work" but it would make mostly useless A4000.
