Sure it could be a compiler error. I know of at least one language
for which that is the case, and there are probably others.
(I'm not sure, but Java may be one of them?)
Note that type correctness (defined in the dynamic sense) is also
undecidable -- yet there are certainly *lots* of languages for which
the compiler enforces type safety at compile time.
