No, Leon was never a Sage. He was a Hero, he then evolved into a True Hero during his battle with Kazarem.

Heroes are different. Heroes are designated by the World System and given a Hero's Egg to in turn hatch. Leon explained prior to his meeting with Rimuru that he is a World Traveler, but instead of being summoned or reincarnating, he fell through a rift in space with Chloe. He ended up stablizing his own energy through force of will and went to the Dwelling of the Spirit to gain the blessing of the Spirit of Light as well as take possession of the Flame Giant Ifrit.

Leon from then was personally taught. Mastering magic and various forms of combat to become A-Rank of his own accord. Similar to Hinata. But he gained a Hero's Egg during this period, meaning he was of rank of a Self-Proclaimed Demon Lord.

Kazarem and him fought and Leon awoke his egg to become a True Hero and gained Purity King Metatron that he used to "kill" Kazarem.

Leon was never a Sage/Saint, instead his long lifespan is due to his True Hero status. If he were to die, he might because a Saint like True Hero Rudra did. However, now that he is a Demi-God, that seems unlikely since he is now a spiritual existance.
