Thanks, Charles--it was simpler than that even. I thought for some
reason that one had to load TIPA in the preamble in order to use it in
Qtree, but everything works without it, so simply removing
\usepackage(tipa) from the preamble in the XeTeX version fixed my
problem.
So the problem here is that TIPA needs to be called expressly even if
the Linguistics module is loaded, if you want to use IPA in syntactic
trees. I have a few shorthand commands for IPA symbols in my preamble,
which also would not work without calling TIPA. But TIPA does not need
to be loaded for XeTeX/non-system fonts even if IPA symbols are called
in qtree, unless there is a conflict between custom-defined function
names and whatever XeTeX introduces (apparently \dz{} is taken, for
example).
For the two or three people in the world using LyX with IPA and
syntactic trees, I am including two example files, one that uses Arial
and another one that uses plain TeX with the linguistics module.
