David Silver has said that explicitly. But "RL" is currently used to describe both problems (MDPs etc), and solutions (RL algos). RL problems are defined very broadly and have so many subtypes (episodic/non, with/without goals, continuous/discrete, ...) that you can frame most things as an RL problem. And "AGI" would by definition be able to solve any RL problem. So imo to some extent this is tautological.
