Why not just check the labeltext?
\define[1]\MyConversion
{\doifelse{#1}{1}{ONE}{#1}}
\define\CheckedConversion % #1 number
{\doiftextelse{\labeltexts{chapter}}\MyConversion\numbers}
\defineconversion[CheckedConversion][\CheckedConversion]
\setuphead[chapter][conversion=CheckedConversion]
\doifmode{label}{\setuplabeltext[chapter=CHAPTER~]}
\starttext
\chapter{Cool}
\chapter{Cat}
\chapter{Mouse}
\stoptext
compile with and without --mode=label.
