Use your employer's credit card to book the Priceline prepaid (or any other prepaid reservation setup).
When you pick up the car, you will need a credit card in YOUR name, regardless of the prepayment status. This is in case you damage the car or keep it past the return time. Also they'll try to sell you prepaid fuel, etc.
Preferably this card is not a debit card by the way. Some locations will take them and some won't.
As long as you don't keep the car over, damage it, or buy the prepaid fuel or other add-on stuff, nothing will be charged to the card in your name.
Note that in this scenario you will NOT be able to rely on any credit card provided rental car loss coverage, from either card. You should make sure that your employer's auto insurance covers rental cars when driven by employees on company business. Otherwise you may need to buy coverage from the rental agency. Your personal auto insurance if any will likely not cover you for that use.
