The arguments seems to be procesed as a argument for discretionaries.
The following works but it is no real solution for the problem.
\unprotect
%\beginETEX \detokenize
\def\installdiscretionaries#1#2#3%
{\setevalue{\strippedcsname\mathmodediscretionary\string#1}
{\detokenize{#1}}% \setvalue {\strippedcsname\textmodediscretionary
\string#1}{#3}% \catcode`#1=\@@active
\scratchcounter=\the\uccode`~
\uccode`~=`#1
\uppercase{\unexpanded\def~{\discretionarycommand~}}%
\uccode`~=\scratchcounter}
%\endETEX
\installdiscretionaries || \compoundhyphen
\protect
\def\room#1{\starttable[ s0 |r|l|]#1\stoptable}
\def\student#1#2{\NC#1\NC#2\NC\MR}
\starttext
\room{
\student{A}{B}
\student{C}{D}
}
\stoptext
