Technically, yes, but I recommend against that because CentOS7 and
the unspecified RHEL version might have different glibc versions (thus
different collations, and so PKs, FKs, queries, etc might fail).
OTOH, *logical* replication would work just fine between CentOS7 and your
unspecified RHEL version. (Lots of metadata updates would complicate that,
though.)
