The FLOWR is not likely to make it faster, as it has to do the same amount of
work.
I think you said that conceptDef is a fragment root, is that right?
//conceptDef looks for all conceptDef elements at all levels of the tree. If
you know the path to your conceptDef elements, that might help, as it will only
need to look where you tell it. For example:
doc("/NDFRT/NDFRT_Public_2009.05.12_TDE.xml")/foo/bar/conceptDef
[empty(definingConcepts/concept)]
If you know something more about the content of definingConcepts, you might be
able to do something clever in your test as well.

...just a suggestion, but try rewriting it as a flowr expression, such as:
for $c in //conceptDef
where fn:empty($c/definingConcepts/concept)
return $c
