You can always check the weird contents of definitions by \meaning... or
\tracingmacros.

I don't know what you want to achieve but maybe this hack keeps you
going...

\input eplain
\def\fileword{file}
\definexref{label}{myfile}{file}

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

\xrefn{label}
\edef\tempb{\jobname}\edef\tempb{\meaning\tempb}

See \ifx\tempa\tempb this file\else \ref{label}\fi.
\bye
