Does Skylake U series processors and Kaby Lake Refresh U series processors have the same pinouts?

I am asking this question because in the tech blogs, they say that I can use a board that was made for Skylake processors for a Kaby Lake processor, and Kaby Lake and Kaby Lake R are identical to each other in terms of pinouts. So, can I use a Kaby Lake R processor on a Skylake board? (This is a BGA CPU swap.)
