No, because as he stated before, the thing is going to hit the Earth in 10 years. If you wait around for 10 years, it's already too late. A 300-mile-wide asteroid is huge, that's the size of a dwarf planet. At the last minute, you'd need an astronomical (literally) amount of energy to change its trajectory. Even if we learned of such an impactor today, we'd likely be screwed because our current tech just isn't capable of moving something that big enough, even with 10 years of advanced warning. (I might be wrong about this, but I doubt it; even exploding a whole bunch of giant nukes probably won't change its course enough.) Maybe if we had 100 years' notice, it'd be enough. Technology will surely improve in 10 years, but the laws of physics won't. It takes energy to move mass, and lots of energy to move a huge mass. I really do not think we're going to invent warp fields in 10 years like they did in the ST:TNG episode with a de-powered Q and use that to magically reduce the mass of the asteroid.
