This will not work, the Scheme unquote, eval, and
the like have absolutely no connection to the corresponding
ones in the macro-expander.

This happens only if you edit the parameter in the version of
the macro without <quote-arg|...> (for some reason I don't fully
understand, to be honest...).

If you want to call the macro-expander from inside Scheme,
use (texmacs-exec x). For example, you could try :
<<
(tree->stree (texmacs-exec '(underline "abcde")))
>>

inside a Scheme session.
