Definitely, just make sure to mention your channels name at the beginning of the video and maybe at the end when you make the call to action to like, share subscribe so that the YPP reviewer has no doubts it's your channel, especially if you don't show your face on cam. You can also make a desktop wallpeper from your channels logo if you think your desktop will be seen while you screen record your tutorial. As to how many tutorials you should upload before requesting monetization, well, I'd say at least 3 videos or as many as needed until your reach the thresholds.
