Cubase 6.5 on 2 platforms

I I’m the happy owner of a Cubase 6.5 on an iMac. Can I run Cubase on my Macbook, too. I have an USB elicenser sitting in iMac.

Yes, move the USB key from iMac to MacBook.

and working with them at the same time? Do I need a second cubase licence? Got 2 studio’s in one room. Mastering and composing. Need to split the licences on several dongles then.
