Can “Business Class” and free users share boards?

[Brian Berger]

If I pay for Business Class licenses for my core five-person team, can I still invite free users (e.g. freelancers) to join certain boards? 

What sort of limitations would I encounter with a mix of paid and free users in our workspace?
