I don’t know, but even if they could do it, they had no reason to. So we can’t really tell.
The real question is—if they really really wanted to and had a book of helpful tips, could they have made decent enough wire? (And could they get copper in sufficient quantities? By Roman times they certainly could.)

Could they make it thin enough (even with insulation) to be able to fit large amounts of windings?
ie, assuming they had reason to try, could they do it based on what we know of their capabilities at the time?
Incidentally, a radio would be much cheaper to make and almost certainly within their capabilities.
