You can, trivially, so trivially that the community has a phrase for shaming people when it happens: "Not your keys, not your coins."
One of the thorniest problems in credit history management in the US is that credentials are given to people who have apparent and actual authority to transact on behalf of other people at the time of the credentials being given but who do not have it at the time of credentials being used. The paradigmatic example is parents using their childrens' SSNs/etc to open accounts, which is routine, legal, and must be a supported use case and, btw, is also an enormous fraud vector. Related vectors include commingled finances of married couples needing to be extricated post divorce and elder abuse.
Blockchains do not solve for these issues, and the community's insistence that they do does not do it credit.
