Can I use a different Apple ID just for Messages?

My work iMac is logged into iCloud using my personal Apple ID, which I use for my personal iPhone. This has been convenient, as I can use the Messages app on the iMac to easily read/write text messages sent to my iPhone. I would like to create a new Apple ID just for my work, and have my work iMac log into that, so that there is a cleaner separation between work and personal, and, I'd be able to have the iMac backup files to the iCloud (currently I have that mostly turned off, so that my work iMac does not use up my 200 GB iCloud storage allowance.) But I'd like to be able to keep using my personal Apple ID for Messages. Is that possible? Or will it confuse the iMac? I thought I should ask before trying.... Thanks.
