\ConTeXt is defined as “Con\TeX t” and \TeX uses kerns and boxes,
both of which suppress hyphenation. AFAIK there's no easy way around
it.

That having said you can surely redefine the \TeX macro to include
custom hyphenation points using \discretionary. Here an example
which inserts a hyphenation point after the “T”:

\unexpanded\def\TeX
  {\dontleavehmode
   \begingroup
   \setbox\scratchbox\hbox{M}%%
   T%%
   \discretionary{-}{}{\kern-.1667\wd\scratchbox}
   \lower.5ex\hbox{E}%%
   \kern-.125\wd\scratchbox
   X%%
   \endgroup}

\starttext
  \hsize\zeropoint
  \ConTeXt
\stoptext

My help is conditional in this case. Don't ever let me know *why*
you actually want to do this ;)
