Yes, but...
"The handle must have the PROCESS_SET_QUOTA access right.
For more information, see Process Security and Access Rights"

And there the rabbit hole opens...

It does appears to be better documented than the last time
I looked:
"PROCESS_SET_QUOTA (0x0100) Required to set memory limits using
SetProcessWorkingSetSize."
   ... should be used with
"To retrieve a process's security descriptor, call the
GetSecurityInfo function. To change a process's security
descriptor, call the SetSecurityInfo function."

I expect it wants the executable run by an Administrator,
but that would only be a temporary nuisance.
