You can, and people have had swapping long before virtual memory. Most
ucLinux platforms can't swap because they can't dynamically relocate code.
Linux 8086 can swap because it can use CS/DS updates to relocate code/data.

isnt entirely in memory. With that constraint you know it won't suddenely
want data you don't have
