Interesting. Would this have applied to other theropods too?

Most likely, though it may have been especially important for tyrannosaurs given their very large thick skulls.

I wonder if a connection to metabolic rate could be drawn from this new data...

Despite the dumb title of the article, the study has tyrannosaurs as simply one data point amongst a bunch of extinct and extant skulls they analyzed. Most theropods had this mechanism, as did pterosaurs, archosaurs, and crocodylians.
