These cores are typically licensed with class/restrictions so in absolute terms yes but in the financial engineering of how the system is delivered with excess and restricted hardware no (see core types on the prior/shipping generation here https://www.ibm.com/downloads/cas/6NW3RPQV)

There are probably design reuse and RAS considerations that make it not currently worthwhile to i.e. have a distinct physical design for SAP or whatever cores.

[sillywalk]

I don't know if it's still the case, but in terms of RAS, the Z/Series CPUs from ~2004 had duplicated/compared instruction-fetch/decode and execution units.
