I've used serial ports just fine on CentOS 7 (haven't had a physical
CentOS 8 system so far, so can't say there, but have used serial
consoles on CentOS 8 VMs), as well as newer Fedora (similar but newer
kernels).  Are you sure you weren't doing something in an unsupported
and/or undefined way that just happened to work on CentOS 6?
