The Shimano website lists the [RD-M5120](https://bike.shimano.com/en-AU/product/component/deore-m4100/RD-M5120-SGS.html) for use with 1×10, 2×10 and 2×11 drivetrains. Is there any reason why it wouldn’t be compatible with a 1×11 drivetrain with a 11-42 cassette (34t chainring)?

nope, no reason it won’t work. Go for it.
