Not likely. Most large corporation IT departments routinely wipe employee hard disks as soon as they recover the computer in order to mitigate the possibility of the employee later using somthing on the hard disk to sue the employer.
Even if there were incriminating files on the computer -- now that it's no longer in your hands, who is to say that the files weren't downloaded by someone in IT. A good computer tech can modify the file dates, so that's not reliable evidence.
Finally, remember that law enforcement needs a better than 50% chance that you've committed a crime to arrest you, and proof beyond all reasonable doubt to convict. So, making a case here, without some really good evidence would be a low probability outcome for a public prosecutor who has better things to do with taxpayer funds.
Prosecutors keep their job by winning cases, not by charging defendants and then losing.
