The space is inserted by TeX when characters in different lines are touching.

You can avoid this when you put everything in a single table. You should also avoid
to use brackets as delimiters for text, use normal braced arguments why can be
grouped without problems.

\startsetups[arde]
  \setupTABLE[c][1][rightframe=on]
\stopsetups

\def\startarde
  {\bTABLE[frame=off,width=.5\textwidth,setups=arde,split=yes]}

\def\stoparde
  {\eTABLE}

\define[2]\arde
  {\bTR
     \bTD#1\eTD
     \bTD#2\eTD 
   \eTR}

\setuptolerance[tolerant,stretch]

\starttext
\startarde
\arde{\input knuth }{\input knuth }
\arde{\input knuth }{\input knuth }
\stoparde
\stoptext
