If the 100 years was for another interstellar asteroid, no. If the 100 years is not a straight line leading outward but rather 3-5 orbits of an inner system rock then yes, we could detect it.
3-5 orbits is around the time one of the subtle re-direction plans needs too. If you had only 1 year's warning the answer is going to have to be nuke it and nuke it again to make the pieces smaller and more widely dispersed. You can get 6-10 warheads on a MIRV bus you could adapt for such a mission. Use all of them in succession.
