No, you cannot. You may have tried using the Apple Pencil while it’s charging and noticed that it doesn’t work. Don’t worry; there isn’t anything at fault with your stylus. The Apple Pencil simply does not work when it’s charging.
While the Apple Pencil is charging, the drawing functionality is disabled for performance reasons. So, it’s by design that you can’t take any notes while it’s connected to the Lightning connector.
But the good thing is that it can be charged very quickly. You can get around 30 minutes of charge in about 15 seconds. Also, the Apple Pencil is fully charged within 15 minutes.

You should see the charge status appear at the top of your screen. If it does not appear, make sure that you turn on the Bluetooth connection.
How to Charge the Apple Pencil Faster
Apple Pencil charges faster when you have its Lightning connector directly inserted into the iPad Pro Lightning port. It goes much faster than using the adapter.
Within about 2 minutes, you can get an extra 15% charge which allows you to work with it for 2 more hours. Apple also claims that within 10 seconds of charging it this way, you could get 30 minutes work out of it.
