No... not without some non-Apple software that I have no experience with, and that may not work in the future. Something called Luna Display I believe.
You are thinking about Target Display Mode: Use your iMac as a display with target display mode - Apple Support. It was limited to a few specific Macs and commensurately few operating systems, and your Macs are not among them.
