Can Carol correctly answer “no” to this (yes/no) question?

Both Yes and No are the wrong answer proving that the question is
incorrect when the context of who is asked is understood to be a
linguistically required aspect of the full meaning of the question.

Wrong, the correct answer is "no", Carol cannot correctly answer no.
 

Thus Carol was asked a question such that both yes and no
are the wrong answer from Carol. Linguistics understands
that the context of who is asked a question is an element
of the full meaning of this question.
