Yes but some things have changed and you will have to do some Googling. It's a bit frustrating though.
It's perhaps not a bad thing to know both as RHEL8 likely won't overtake RHEL7 in terms of usage for a while (perhaps years).
I'd argue that RHEL8 isn't even ready for wide adoption yet anyway because many tools don't support it yet (e.g. Spacewalk/OVirt).
Edit: Linux Academy lists the following new things in the RHCSA for RHEL 8: Adjust Process Priorities, Journals, Disk Compression (Virtual Disk Optimizer), Using the AppStream (yum modules), Adjust Real Time Process Priorities (chrt), AutoFS and Extending Virtual Disks (LVM/VDO).
