Well i think that the term Haki is known to by high class pirates. Ivankov must've told Sanji about Luffy's HH during his attempt to stop Ace's execution and so did Mihawk to Zoro. But then again Zoro has HH himself as you see him use it against Pirate Hunters in Sabaody Archipelago. Or it may be that Red Leg knew about it and told Sanji when he was younger...the possibilites are endless...
