The malicious code could just move the entire original bundle
wholesale. Code signature check still sees the original bundle.

Unless, of course, the app checked its code signature.
Ok, I'll bite. How does the real binary checking its code
signature detect the case you just described? Its 100% byte for
byte the original executable, its just been moved somewhere else
and as far as I'm aware, code signatures do not include your
location on disk.
You check the signature of the .app bundle, not the executable itself.
