If you misrepresent that you are authorized by the company making the takedown request, that's literally the only thing that the DMCA considers to be perjury.
So weirdly enough:
* Not owning the copyrighted work and claiming you own it = Okay
* The work you're taking down not even being the claimed copyrighted work = Okay
* Saying you're authorized by the company to file the notice, and you're not = PERJURY
