No, you can't do that. /boot is special and needs to be a separate partition. The most likely cause of your problems is that you have multiple kernels installed - when you boot the machine do you see multiple versions on the grub boot screen? If you don't need the previous versions then they can just be deleted using yum: do 'rpm -q kernel' to see which kernels are installed and 'uname -r' to see which version you are currently running (it should be the same as the highest version installed). You can then use 'yum erase ...' to remove the old kernels. It's always handy to have a version or two old ones in case of emergency so I always leave three on a system. The multiple versions installed of some things - i.e. the kernel - is controlled by a yum variable in /etc/yum.conf called 'installonly_limit'. It's probably set to 5 at the moment, you can set it to 3 safely and that is usually sufficient to stop /boot filling up. P.
