No. Architecturally all Intel provides is the physical address in MCi_ADDR.
To do anything with that you are into per-system space, and the
registers that define the mappings are not necessarily available
to OS code ... sometimes they are, and sometimes they are even
documented in places where Mauro can use them to write an
EDAC driver ... but there are no guarantees.
