No.  In theory the kernel could make use of TrustZone if it is not
locked down by vendor firmware ... but it is hard to make effective
use of it in a large general-purpose software stack like the Linux
kernel.

In consumer devices, TrustZone is often locked down by vendor
firmware, and then Linux can't play with it anyway.

What are you trying to achieve?
