No I don't think so, a Tomb Raider developer a while ago referred to Uncharted as being heavily PS3 optimised with regard to its graphics, this while stating Underworld is a 360 lead project and the game's assets and the general game engine (while using PS3 friendly coding methods, which lead to 360/PC speed benefits as well) are designed around the 360's strongpoints and abilities.
Although Uncharted covers the same genre (Indiana Jones inspired action-adventure), I think it's very different from any Tomb Raider game.
