Another way is to use the string library from lua to replace μμ with mm:

\unprotected\def\interfaceddimension#1%
  {\ctxlua{commands.interfaceddimension(\!!bs\detokenize{#1}\!!es)}}

\startluacode
function commands.interfaceddimension(str)
    if string.match(str,"\\") then
        -- dimension or macro
    else
        str = string.gsub(str,"μμ","mm")
    end
    tex.print(str)
end
\stopluacode

\setupbodyfont[palatino]

\starttext

\def\foo{4mm}
\def\bar{\textwidth}

\scratchdimen\interfaceddimension{2mm} 2mm: \the\scratchdimen\crlf
\scratchdimen\interfaceddimension{1μμ} 1μμ: \the\scratchdimen\crlf
\scratchdimen\interfaceddimension\foo  foo: \the\scratchdimen\crlf
\scratchdimen\interfaceddimension\bar  bar: \the\scratchdimen

\stoptext
