Megaupload can bring a civil suit against Universal but these proceedings cannot lead to a felony conviction, which once again is a criminal sanction.
Google, or any other corporation or citizen, cannot bring criminal charges... we can only file civil actions and report crimes to authorities in the appropriate jurisdiction (the police or FBI for example) who then report to prosecutors who decide whether to bring charges. Perjury is not just an offense at some specific person or organization, it's an offense to society, and society punishes through criminal prosecution (United States v. You, Commonwealth of Pennsylvania v. You, etc.).
At least that's my "Civics 101" level understanding.
Maybe Universal merely broke their contract with Google.

(Proving that any given corporate officer had the requisite intent to commit a crime (the 'mens rea') is difficult to impossible, which is one reason why corporations can be tried in criminal court.)
Not sure you could imprison a company though. That'd probably be the same as the death penalty.
