(I am not a lawyer, but did read coverage of the SCO lawsuit extensively)
Falsely claiming to hold copyright in a work to which you do not hold copyright may open the possibility for slander of title (which was one of the claims in the SCO lawsuit).
I would be interested to see some sufficiently-deep-pocketed entity try to use that to turn an automated-DMCA-complaint house into a smoking hole in the ground, pour encourager les autres.
Arguably there may be other causes of action, but for a lone a DMCA takedown notice sans any accompanying threats, I believe Federal law would preempt and you're stuck try to meet the bar of intentional malice or negligence.
(IAANAL, but I listen to a lot of Jay-Z songs so I know a little bit.)
