Yes, of course it could, by making a sintered carbide bottleneck insert, internally grinding/polishing it and precision bonding it into the steel die body.
It would be a lot more expensive than a steel die or a carbide-collared straight case die.
It would also be vulnerable to incorrect setting of the expander, which in sizing a bottleneck case functions on withdrawal, not entry. Once you'd cracked one such carbide die, you'd most likely hesitate to spend out on another. That's probably why nobody (AFAIK 
) makes one.
