Good news, Linux works well on old computers, and in many cases, you can just move the boot drive to the new hardware and you’re good.

If this is about SecureBoot stuff you’d have to get a new motherboard lol which basically means new everything sadly.
You don’t need secure boot or TPM for Linux. So you could switch today, and when you need upgraded hardware, just move the boot drive over.
