I would think so. You can see it in a lot of promo shoots from back then. I don't have a lot of pictures on hand to show this, but I've certainly seen it before. From my personal collection, here's a picture of a manual from Nazo No Murasamejou on Famicom Disk System:

If you look in off-screen photos old videogame magazines and manuals, you'll see a ton more with scanlines. It was typical in the NES days specifically before developers had screenshot tools and relied on photographs to make their promo stuff.
