Can I use the XX SL or other SRAM Eagle Transmission T-type chains on my AXS road drivetrain?

No. While the Eagle T-type chains build on the technology of our robust Flattop road 12-speed chains, there are some differences that make them incompatible. We strongly recommend only using the T-Type Eagle Transmission chains with the Eagle Transmission system, and the Flattop 12-speed road chains with the road drivetrains to avoid potential premature wear or damage to other components.
