Question: what is the difference between a 10 speed and 11 speed cassette?
Answer: Chains for 11-speed systems are around 5.4mm wide on the outside, vs. around 5.9mm wide for 10-speed ones, so that's 0.25mm narrower from the center of the cog tooth to the end of the chain pin on each side. That's not enough to likely even be noticeable in any difference in how it passes through the jockey wheel cage.
