Can I use a higher or lower speed chain with Shimano ULTEGRA REAR DERAILLEUR MEDIUM CAGE 11s?

No. Shimano ULTEGRA REAR DERAILLEUR MEDIUM CAGE 11s is an 11-speed component and needs an 11-speed chain. Chains for different speed counts have different external widths and inner-plate profiles, which causes poor shifting or interference with the neighbouring sprockets.

No. Shimano ULTEGRA REAR DERAILLEUR MEDIUM CAGE 11s is mechanical, cable-actuated. Electronic groups use internal motors and proprietary signalling, so there is no mechanical or electrical path between the two.
