No.

Irene was the Dragon Queen of that kingdom from 400 years ago, which no longer exists, hence why even she refered to herself only as the former Dragon Queen. Not to mention that she wasn't actually the queen of the Dragons juding by what we saw of her kingdom, but that was just how the Human ruler was called there due to the alliance with the Dragons, but the Dragons as far as I can tell were still ruled by Belserion and not her. He listened to her advice out of respect for her position and gratitued to Irene's father, not because he was her subject.
