I don't know about a copy of CP/M but it does ahve a table of all 
the addresses inside CP/M (CCP, BDOS and BIOS)that get relocated.
If the system and MOVCPM are from differnt systems (say kayII and 
a 4/84) it's very likely the BIOS varies enough that the BIOS 
will get mashed.  The serial numbmer (besides copyright) was to keep
the two matched or prevent a mess.

There is that but it's a seperate issue.
