There is nothing really "wrong" with using a newer kernel.  It just 
requires more work on your part.  The beauty of the stock binaries 
(including the kernel) is that you can simply type "yum update blah"  
and know with a fairly high degree of certainty that the system will 
continue to work, that relevant security fixes have been maintained, 
dependencies with other programs maintained, etc.  If you roll your own 
kernel from  more recent virginal source,  it is still likely to work 
fine, but you will have to mind all those other issues yourself.  Unless 
you have some device  that isn't working properly with the stock kernel, 
it probably isn't worth the hassle of doing things yourself.
