Yeah Dota has loads of easter eggs, and some from the Diablo series.
Eaglehorn, Messerschmidts, Buriza and of course the infamous "FRESH MEAT" with Pudge's ulti are the ones I can remember atm

The biggest cross-reference is Leoric, the Skeleton King in Warcraft 3's DotA. Which was referenced from Diablo I. Which is, again, in Diablo III =]
