New iMac coming. Old computer is running Big Sur Beta. Install Beta on iMac first?

I am receiving my iMac today. Before ordering the iMac, I loaded the Big Sure Beta Public Beta on my MacBook Pro. Its running pretty smooth for me.

Question. Can I put the public beta on the new iMac and then transfer my data/programs from the MacBook Pro?

You cannot install Big Sur 11 beta 5 on the new iMacs yet...

General
Known Issues
Important

macOS Big Sur 11 beta 5 is not currently supported for iMac (Retina 5K, 27-inch, 2020). If you encounter an installation issue on iMac (Retina 5K, 27-inch, 2020), you need to reinstall macOS Catalina. Hold down the power button to force restart, and then press Command-R immediately after turning on your Mac. Then, follow instructions to reinstall macOS Catalina from Recovery.

Why would you want to install a beta version of MacOS on all you Macs?
