Probably. It will often be the case that the disabled core is defective, maybe not fully dead, but it did not pass all of its tests. It is common practice to recycle multicore CPUs with one bad CPU and sell it as a lower performance part. Similarly, chips that won't run at full speed, but will pass all tests at a lower speed, may be stamped as a lower performance part and shipped as that. It makes good business sense to do this since it lets them recover the otherwise wasted production costs on these partially defective devices. They may also disable the 4th core even if works perfectly, and sell it as a 3 core device, when they have an order for the tricore that needs to be shipped and not enough quadcore chips on hand with one bad core to fill it.
