Centrino is a platform-marketing initiative from Intel. It is not a mobile CPU - rather, the term covers a particular combination of mainboard chipset, mobile CPU and wireless network interface in the design of a laptop personal computer. Intel claimed that systems equipped with these technologies should deliver better performance, longer battery life and broad wireless network interoperability.
The Core 2 brand refers to a range of Intel's consumer 64-bit dual-core and 2x2 MCM quad-core CPUs with the x86-64 instruction set, based on the Intel Core microarchitecture, derived from the 32-bit dual-core Yonah laptop processor.

So the Texan was wrong - and so are you!
Centrino is an "architecture" for laptops. Core 2 is a family of processors, some of which may be incorporated into that architecture.
