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.
