Is there a way in emacs-lisp code to detect if a file binary, that is
it does *not* contain a correct multi-character coding.
Or can every possible combination of bytes always be correctly decoded
by some character coding?

Yes, it can. For all one-byte encodings of the iso-8859-x family, each
byte represents a valid code point, for example. In utf-8 there are byte
sequences which can't (shouldn't) happen.
I think the only way to gain some confidence is by statistical analysis
of the text.
