No. What you can do is reformat the whole rig and reinstall the OS. That'll give you a fresh brand new rig, but, you will not have any of the old data available to you. As long as you are just an employee of the organization, it basically, is not your problem.
If it's a machine made by Compaq or Acer or one of the brands, meaning, if it's a branded rig, all you need to do is just recover the machine to it's factory settings, but, once again you'll not have any old data available to be used. But, your drives do get free for further use.
PS: I for got to ask you , if you have tried to disable the Bitlocker Encryption from the Control Panel??
