Home license, multiple users on linux?

I have a home license and have had it installed on two computers (my laptop and another machine my kids use for school). I recently got a linux machine to replace the kids computer and upon install see that I am limited to one user name? So I can use it, but my kids can't, or vice versa. My question is, can I deactivate my laptop and activate another user account on the linux machine?

This seems like a pointless restriction, since we could make an extra shared account on linux just for matlab, which would simply be very inconvenient.
