I'd say no. IDHMBWM, but as I recall, Secret Word can be used with any spell you know. Magery (One Spell) would be a very different ability. And even then, I'd probably disallow an upgrade from Secret Word to Magery, as it has a different flavor – but that's totally up to the GM and what does Magery represent in-game.
