Yes you can do it.
Update Mailbox 1st and then go to CAS server
Prereq .net 4.7.1
1. Take backup of your AD (system State) & Exchange DBs
2. Upgrade your schema 1st and allow for replication to your other DC
3. Now upgrade your passive mailbox server.
4. Now move active DB's to passive server & upgrade the last remaining server
5. Now go to CAS servers.
