no, with \includeMPgraphics not being expanded before testing on mptex runs:

\long\def\writecheckedMPgraphic#1%
  {\ifforceMPTEXgraphic
     \global\MPTEXgraphictrue
   \else
     \global\MPTEXgraphicfalse
     \edef\ascii{#1}\convertcommand\ascii\to\MPascii
     \the\MPTEXgraphicchecks\relax % \relax is end condition!
   \fi
   \flushMPTEXgraphic % verbatimtex etc
   \writeMPgraphic{#1}}

\startuseMPgraphic{standalone}
    draw textext("whatever") ;
\stopuseMPgraphic

\starttext

% \forceMPTEXgraphictrue

\startMPcode
    fill fullcircle scaled 2mm ; \includeMPgraphic{standalone}
\stopMPcode

\startMPcode
    draw fullcircle scaled 2mm ; \includeMPgraphic{standalone}
\stopMPcode

\stoptext

one can always force tex runs with: \forceMPTEXgraphictrue
