When I changed '\starttabulate' to '\starttabulate[|l|p|]' in your  
solution above, it broke.
Try to escape the |, it's a active character in ConTeXt but this
could work (untested):
\def\testmacro
 {\bgroup
  \catcode`\\=12
  \catcode`\|=12
  \dotestmacro}
And now with a catcode table.

% redefined version of \startcatcodetable

\long\def\startcatcodetable#1#2\stopcatcodetable
   {\bgroup
    %\catcodetable\scratchcatcodetable
    \the\setdefaultcatcodes
    #2%
    \savecatcodetable#1\relax
    \egroup}

% the new catcode table

\newcatcodetable \testcatcodes

\startcatcodetable \testcatcodes
     \catcode`\\ = 12
     \catcode`\| = 12
\stopcatcodetable

\def\testmacro
   {\bgroup
    \setcatcodetable\testcatcodes
    \dotestmacro}

\def\dotestmacro#1%
   {\ctxlua{d='\luaescapestring{#1}'}
    \egroup}

\starttext

\testmacro{\starttabulate[|l|p|] \NC knuth \NC \input knuth \NC\NR  
\stoptabulate}

\ctxlua{tex.sprint(d)}

\stoptext
