Yes, you may. My understanding is that you won't invalidate your warranty simply by opening your case. However: Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard. (Repeatedly touching a metal case part is not sufficient mitigation with modern components.)
Hi   I am planning to buy a Vostro for work from home. The machines come default fitted with a 512 GB SSD, so can I upgrade to a 2 TB later, withut voiding the warranty?   Thanks in advance.   regards SNM
Can I upgrade a Vostro 5630 with a 2 TB SSD later after buying?
