you can grep the kernel sources for this string, and replace it with whatever you want, and then recompile your kernel. Usually replacing a string directly inside a binary (though it is technically possible), especially for the kernel is a very bad idea

The message is in /arch/.../boot/cpu.c in the linux kernel source. You can modify it, recompile the kernel and install the new kernel.
