I just purchase a really clean 1993 Honda accord SE coupe that has the issues with the TCM. I inspected TCM board and it looks awful. So when I purchased it, it had a 28100-Px0-732 tcm in it. Will the 28100-px4-732 tcm work? Are those interchangeable? I apologize if this post is in the wrong section. I have scoured google and I just haven’t been lucky finding an answer. Any help would be greatly appreciated.

PX IIRC is for the 90-93 Model Accords.
Each year will have slight differences but it should work fine.
A 94/95 might not work properly as the CD Accords don't have the Sport/Hold button found on the CB Accord shifters.
