You can not only run a different kernel but in fact two kernels at the 
same time, though I am not quite sure  if the usual license  allows 
that. You do it as follows (I am describing how it works under MacOS X, 
but it ought to be the same for other OS's).  Choose "Kernel 
Configuration Options" from the Kernel menu. Click on the Add button. 
Name your new kernel. Make sure that Launch On Local machine is chosen 
(it is the default). Click on the Advanced Options tab. In the field 
"Arguments to MLOpen" insert the proper path to your new kernel. Now if 
you go again to the Kernel menu you will find that under Start Kernel, 
and Notebook Kernel items you have two kernels. Create a new notebook. 
 From the Notebook Kernel menu choose the new kernel. If you did not make 
a mistake in inserting the full path to the kernel in "Arguments to 
MLOpen" all computation in this notebook will be performed by the new 
kernel while those in other notebooks by the default kernel. Of course 
you need enough RAM for this to work. Other than that, you can just 
quite the default kernel first.

I have never really found out whether the owners of single licenses are 
licensed to run their own old kernels together with new ones. It is 
actually a very reasonable thing to do when new kernels (or new 
FrontEnds) contain bugs not present in previous versions.
