If unicorns can survive if their horn is still intact, that means if, say, Twilight got her horn cut off and then fell into a lava pit, her horn would regenerate into her. Or if Celestia was blasted to pieces by Chrysalis but her horn was still intact, would it regenerate?

Of course we haven't had a lot of instances of named characters being killed (except Fuzzy Slippers) or of unicorns having their horns cut off, closest we see to that is Discord making Twilight and Rarity's horns disappear. When Sombra's horn was cut off he was in shadow form, which was a result of him being disembodied by Celestia and Luna, and he regained his physical form in the end but if he hadn't I bet he'd have exploded in a flash of light (or rainbow shockwave) without seeing his horn go flying
