OCLP for booting existing OS X on a different machine

I have an existing installation of Big Sur for my late 2012 MacBook Pro on a external SSD drive (I use this every day). Installed this with the Macbook Pro. Can I use OCLP on my old Mid 2011 iMac to boot this OS without a new install? I would like to switch between the two Macs with the same bootdrive, same configuration and same userprofile. Did not find informations about this anywhere. Thanks in advance.
