You can use the “list” and “marking” keys to set separate entries for the
header and TOC.
\setuphead
[chapter]
[after={\blank[fixed,2*line]},
header=empty,
align=middle,
style={\setcharactercasing[WORD]}]
\setupheadertexts[chapter]
\starttext
\completecontent
\startchapter[title={First chapter title}]
\dorecurse{10}{\input knuth\par}
\stopchapter
\startchapter[title={Second chapter title\\which is very long},list={Second
chapter title …},marking={Second chapter title …}]
\dorecurse{10}{\input zapf\par}
\stopchapter
\stoptext
