Changing macro definitions doesn't break the stable ABI, as long as the old macro expansions still do the right thing.
To me, it looks like a bad idea to change macros. Imagine that the PyCFunction_Check macro changes in Python 3.8. Then an extension module compiled on 3.7 (but run on 3.8) would behave differently from the same extension compiled on 3.8. I cannot imagine that this is in line with the "stable ABI" philosophy.
Jeroen.
