Yes, the cassette spacing on the Shimano and SRAM 10 speed cassettes are identical. The SRAM cassettes don't need the 1mm spacer that Shimano cassettes do though. The pull ratio is irrelevant if you're using a matching SRAM mech and shifter, obvs. A 10 speed Shimano shifter (other than Tiagra R4700) works perfectly with a 9 speed MTB rear derailleur and a 10 speed cassette. Otherwise, I don't think the road and MTB parts are compatible, except of course for Di2.
