For example, I use mail.exampl.net as the FQDN for the mail sever,
but if I have a hosted domain at example.com can I have its MX set to
mail.example.com and point to the same IP without issue,
or do I need to do something in postfix to account for this?

You can have mail.example.com and www.example.com and www.otherwebsite.comall
on the same server/IP.
otherwebsite.com can set its MX record to mail.example.com and you don't need
to do anything extra
in postfix other than set it up to work for mail.example.com.

Yes, I have been doing this for many many years, what I have not done
previously is create an MX record for mail.otherdomain.com pointing to the
same IP as main.maindomain.net
you only need MX for mail.example.com if you do use @mail.example.com in
mail AND mail.example.com is NOT the MX for mail.example.com
Or, if you want MX backups for mail.example.com.
If you do NOT use @mail.example.com, you can even point MX to "."
Looks like I am prepared for the switchover this evening (scheduled so I
have a whole weekends to recover from any errors 😃)
