It depends. 

If you are changing the SELinux mode from 'enforcing' to 'permissive' and vice versa, you can make that change active in the running system by issuing the 'setenforce 1' or 'setenforce 0' command, respectively. 

If you want to go to or from 'disabled' or change the SELinux policy you'll need to reboot to activate the change.
