The solution was suggested by Hartmut Henkel in the texhax mailing list.
Here's the hack:

\definexref{label}{\jobname}{}

\def\xrefn#1{%
\edef\tempa{\refn{#1}}\edef\tempa{\meaning\tempa}}
\xrefn{label}
\edef\tempb{\jobname}\edef\tempb{\meaning\tempb}

\ifx\tempa\tempb yes\else no\fi.

Thanks to all, indeed.
