Overclocking laptops in general and especially "office" laptops is never a good ideea.
Cooling solutions on laptops are very size optimized and in 99% cases overclocking will lead to throttling so even if it works, your performance will drop instead of rising.
Bottom line: can you? maybe. should you? hell no.
Best things you can do to upgrade laptops are more ram memory if possible and get a ssd if you have a hdd.
