No, but everything is possible.  I think that making this general will just confuse prople (which has security implications).

At the hardware level, I think that is possible, but a lot of the interesting functionality in a TPM, such as the PCR registers make no/little sense in that case.

The PCR registers contain SHA1/SHA2 checksums from the bootup process, and also possibly from when the SENTER instruction was executed (late secure launch, after normal BIOS boot when Intel TXT is used).

It is entirely unclear what kind of threats recording that kind of information in two devices would deter.  OTOH, the TPM also contains other functionality such as a random number generator and general crypto functions.  These are all dead slow, but for example the random number generator could in theory be accessed from multiple TPM.

What is happening is that the TPM is getting moved into the CPU and off the motherboard, not that multiple TPMs are available.  If the CPU comes with a TPM, the natural choice would be to just turn off any TPM on the motherboard in the BIOS.
