8 Tuners and minis

Ok so dumb question and it's probably covered here somewhere but I can't find it.

I have a Bolt, a Roamio OTA and 3 minis. That gives me 8 tuners.

Say I'm recording 4 shows on my Bolt thus using all available tuners on that box. Can the minis use the tuners on the Roamio to watch live TV?
