No, a CPU in the wrong place on the chipset won't damage the CPU or the motherboard.

It won’t harm the motherboard, the CPU may not function properly initially, so you’ll likely need a BIOS upgrade. In the worst case, it might not power on at all.
8400 is compatible with LGA1151v2, but an official BIOS update won't work on LGA1151v1 boards. The physical sockets match, though the electrical connections differ. 1151v1 supports 100 and 200 series chipsets, while 1151v2 uses 300 and 400 series. 8000 and 9000 series CPUs require different chipset types. Custom BIOS modifications exist but come with significant risks for such outdated hardware.
