I've heard many times that you can kill a person with a open palm strike to the nose. This is a myth. The nose cartiledge is not strong enough to penetrate the skull. However, a person can die from severe blunt head truama.

I'm not sure this is true. The nose cartilage would only need to penetrate the cribiform plate, which is a pretty thin piece of bone. However, even if it did penetrate, it would damage the frontal lobes, which is not in itself fatal. So you may be right, but I'm not sure about your reason.
