There's distros for this: https://github.com/marmolak/gray486linux https://github.com/marmolak/gray486linux – it's based on Linux 6.7. Never used it; don't know how well it works in practice. But it's the type of thing that can be made to work. Looks like some minimum requirements are a tad higher than the minimum of Windows 3.1 though, so it depends a bit on what you mean exactly with "Windows 3.1 era hardware".
