It's close. The Assembler instructions are the same based on the 370 architecture. The macros differ. Cobol is also very close but without IBM extensions. The EBCDIC codepage differ for german umlaut. About 15 years ago you can IPL MVS on a siemens hardware but require intervention from Siemens.
I never worked on BS2000 just on a CICS-UTM connection. BS2000/OSD the OS is complete different. BS3000 was close to MVS but IBM persue Siemens and BS3000 was dead.
