It might charge it, but not while in use. The LENOVO YOGA 720 supply outputs 45W, so based on my reading a 36W would charge it when the screen is off only.
As for other news from CES I would say that they had a well put together booth with a lot of knowledgeable staff on hand to answer questions. Even someone with an EE degree pushing to specifics on power distribution, which is why I understand the reasons for not trying to push above 36W right now.
My favorite part was their sound demo rooms. They were really quite insulated so you could block out the din of the floor as you listened to the smart enabled speakers.
I also enjoyed seeing the new projector, but was disappointed that it was not even 720 native.
