I think you can... You just need some Responsible Corporate Laptop Stickering!
Grab your Clear Contact paper (available at most general home goods stores like Target and Wal-Mart, it's usually used for covering old cabinet shelves) and a scissors, choose a size bigger than your sticker, cut cut cut...
...place your sticker on the face of the Contact paper and cut around the sticker, peel off the paper backing and spread on your laptop cover as you like.
Ta da!Now you have a canvas for showing off your stickers and if worse comes to worse you can peel it right off.
Re-positionable, removable you've got it all!
