Depends on what you mean by update...
There are custom kernels built on top of that version that can give you possibilities (could also do the opposite depending on the situation and phone) for better performance, battery life, blinking light notifications, and the like, but as far as the actual kernel version itself, that is the last official Samsung one.
Now, there are tons of newer kernel versions than that for your phone, but they would require you to install a custom recovery and a custom version of Android, such as CyanogenMod. This varies vastly from the stock Samsung Touchwiz software that is on there now. Many people find the update to a custom version an upgrade, but it can cause things to work differently or not at all, depending on what it is, as well as enable many more great things and getting to enjoy the newer versions of Android.
