Maybe in 2025 if you're lucky. Apple sure as hell isn't going to release opensource drivers like intel or AMD are doing.
I don't think Apple would be nearly as open this time as they've been in the past. It'll probably be nearly as locked down (in terms of load) as the iDevices are. Not only that, but it will put the final nail in the Hackintosh should they deprecate x86 support.
As much as for running Linux on the iPhone / iPad I bet.
With Bootcamp: Very likely.
I'm not so sure if they'll include it this time, though (still I tend towards yes, but it also will depend on Windows ARM's success).
Current Macs with Bootcamp are already basically useless for running Linux. It is not technically impossible to run but might as well be. The T2 SSD controller actively prevents access by any OS that is not either MacOS or Windows, even with secure boot disabled.
