I believe so.
All you need to do is to "release the license" and in your customer's portal dashboard you'll have a code which you will use on your new computer.
Basically what it will do is to check whether there is any other MAC address is associated with your code.
For instance, in Maya we have a special button on the shelf - "Release the license" once you press it - it sends a signal to Maxwell that your serial number is no longer associated with the current MAC address. So all you need to do is to install it like a new one on your new computer.
Hope it helps,
