My 2 weeks old baby didn't wake up for his feed. Last feed was about 7 hours ago. Should I wake him up or should I let him sleep?

yes at 2 weeks your baby is too small to sleep for so long without a feed. however, if this is a one-off case, then it is fine. i remember my first born would wake up every 1 or 2 hours for a feed in the first few weeks, but in case of my second one, she would sometimes sleep for an entire 6 to 8 hours without feed, in the first month. i was concerned and asked the doc, and he said it was absolutely fine, and that she was just catching up on her sleep. do speak to your baby's doc once. you can try waking him up gently after every 2 or 3 hours, or just let him latch on in sleep and see if he will feed.
