With the exception that EIGRP defaults to classful boundaries, sure. I'm sure you didn't mean to type that, but just in case, yes, you can specify a /32 mask to enable EIGRP on an interface under the router process.
I can't think of any reason that would make you enable OSPF one way or the other (interface or router process) for IPv4.
