As long as you do it as brother and sister and not as lovers, yes.
Your sister-in-law is either the wife of your brother or the sister of your spouse. Your brother-in-law is either the husband of your sister or the brother of your spouse. So your brother-in-law's wife is either your sister or is not related to you. Some people incorrectly refer to a brother-in-law's wife as a sister-in-law.
