No.  A music function is only an input transformation.  But it could
produce a \applyContext call for checking the current state in a
context.  However, I don't think that "DynamicLineSpanner is currently
playing" leaves a recognizable trace in the context properties (I may be
mistaken), so you probably need an engraver as well for doing the
tracking.
