She may have been a woman, but she was the mother to the King of the North and from House Tully, so her words and gestures held meaning. Asking Renly to seize claim to the Iron Throne couldn't have been done by a lesser nobleman in Robb's defenses. Plus, each house's bannermen followed orders from their noble lord, so someone like The Greatjon, for example, couldn't just leave his soldiers under someone else's command while he parlayed with Renly.
