There is a suggestion in Sanhedrin that a wife of a Talmid Chacham does not require a warning for a capital punishment (adultery?) because she knows the halokha. Presumably, her husband taught her or he married a daughter of T’Ch who taught her. So, it is not just Beruriah, it is a presumption about any wife of T’Ch.
