In what sense?  I have used qemu with -net user with my hosts' wifi interface.
However, due to the nature of how wifi works, I think it would be impossible
to setup a bridge (like you can do with a wired lan) and use the tap interface
to provide full access to a qemu guest.  One reason is one-to-one mapping between
a wifi interface and it's AP.

I suspect that using a tap interface, and some ipfilt rules, you might be able
to make this work.  Assuming that the host doesn't have anything to do with
that interface, you could write the ipfilt rules to push all the packets to the 
tap interface with a rewrite rule.  However, I can't give you much help beyond
that.  I don't do ipfilt these days.
