Just to clarify, these kernel configuration options are for when one
builds the kernel for "i686-linux" (Guix parlance) or "i386" (Linux
parlance). This means 32-bit Intel-compatible.
The T400 has a Core 2 Duo 64-bit procesor, so these options won't apply
for you. That's "x86_64-linux" or "amd64", respectively.
However, yes, you can build a custom kernel to eke out some performance
improvements.
