Unfortunately the strict answer to your question is actually yes.

The CPU won't work, mind you, but it does physically fit...

No, the socket is LGA 1151 but the chipset is different: 300-series vs 200. You need a new motherboard.

Why didn't they just use a new socket number for this? Even something like LGA1151B would have made this clear and easier to search product.

Technically its the same socket. But the voltage is different. Coffee Lake consumes more.

You could use Kabylake('200 series') processors in 100 series (Skylake) motherboards with a BIOS update. Both 1151 socket.

Shame this didn't continue.

Its because the power profile of the connectors are different. Its subtle, but it makes it incompatible.
