Probably not.

First article describes how you can turn off Intel's HW RNG.

Second article shows how to hack Intel CPU's via USB & JTAG.

I suspect that this is just the beginning of JTAG-type hacks on CPU's from all vendors.  I spoke recently with a TI IoT chip designer about JTAG, and he seemed clueless, so perhaps TI chips would be a good place to start looking?
