The answer
Yes. Cold storage protects signing keys, not the underlying consensus rules. A chain split may create distinct balances on separate chains depending on their rules.
What to do next
Do not rush to claim forked coins using unknown software or disclose keys to unofficial claiming sites. Verify the chain and wallet support first.
