There may not be a physical compatibility problem, but that does not mean they are compatible. TR4 does not have the same requirements of the motherboard as SP3, so motherboards made to the TR4 spec do not meet the spec for an SP3 cpu and are not considered a valid configuration.
Most of the reason for a new socket designation and forced break in compatibility is because the design spec for the motherboard side has been changed.
You see this with socket 1151, the power spec was changed in line with the higher boosting power requirements on the 6 and 8 core chips, which meant that motherboards designed for the 4 core cpu spec weren't considered compatible.. but if you remove all the safety and validation checks those chips can boot and run on a board that's built well enough to not be damaged by the extra load. But the boosting behavior of those newer chips on older boards is wrong, it doesn't boost properly at stock.
If I had to guess, I'd say the design spec for SP3 motherboards had pci-e requirements good enough for pci-e 4, but the spec for TR4 probably didn't in an effort to make the boards less expensive.
