Sure, but your apps have to be renewed every 7 days (or 365 if you have a developer account).

And, almost more restricting in my experience, you can only have two (2) sideloaded apps installed at a time (3 if you count AltStore itself).

Unless you are lucky enough to have a MacDirtyCow-vulnerable device+OS, of course, but if you are going there why not just jailbreak?
