It is true that the Whiterun guard states that there were no dragons in Tiber Septim's time. However, he obviously didn't know about the jewel of Imperial crown. Nafalar or Nafaliargus, red dragon that was in the employ of Tiber Septim. Even Dragon Atlas of Dragonguard suggest that this dragon still alive and avoided being killed because he got himself employed by several rulers. Plus, Parthunax remained alive ever since Dragon Wars, until 4th era and Tiber Septim definetly knew about him and told Blades no about killing him. Sounds like the Whiterun guard was not as informed, but I don't think anyone besides Blades or true Dragonborn would know that information.
