Is this "can" or "should"? This sounds like the latter.

This does not make the entire operation to fail (and I think the
behaviour you have here is preferrable--we just want to report
without failing the main operation).
But should it be reported as "error: unable to unlink"? It may be
better to give this message as a warning.
