No it wont work, you will need to rebuild the initrd and the required
kernel moduls first.

One way to work around the situation would be to first exclude the
kernel and upgrade everything else to the latest CentOS Release. Then
install the new kernel with a "yum install {kenel-version-release.arch}"
( dont upgrade the kernel, just install the new one - multiple kernels
can co-exist with no issues ). Once you have installed the new kernel,
check your boot loader configs to see what is the 'default' kernel. You
might want to leave default kernel on the old one - till you can get the
new initrd in place.
It would, however, make sense to try find out how the original initrd
was built and what, if any, new modules need to be created first.
