Yes. This change to (mu latin) worked. Thank you so much for the
detailed explanations.
I think it is preferable to use upright greek letters in units.
The shape of (mu latin) in the latin modern font isn't the prettiest
design, but is still better than mixing italic mu with other upright
letters in units.
Besides, I guess, (mu latin) instead of u can be used in text-mode units?

That took some thinking. The error is caused by the \mathcode of µ,
it is "7116, but it should be "0116. The '7' in the current
definition makes it switch along with \fam. \dimensiontypeface
expands to \tf, so \fam is set to 11, and that is \rm.
So you end up with this minimal file:
\starttext
$\rm µ$ % that's U+03BC
\stoptext
The latin modern text (\rm) font does not have a greek alphabet.
If it did, all would have worked ok. Since that cannot easily be
fixed and I suspect most text fonts do not have greek, so changing
the mathcode of the greek characters is probably the best solution
(it affects normal math mode as well, as you can see)
And as an aside, it would be nicer to use U+00B5 (mu latin) in the
units module instead of U+03BC (mu greek).
\def\Micro {\dimensionprefix{\iftextdimensions u\else\hbox{µ}\fi}}
The \hbox is needed because \fam11 is using ec encoding, I think.
(and that is problematic in its own way, but let's not go there)
Best wishes,
Taco
