If you put on enough layers, of course you could. But the amount of extra clothing you would need would be ridiculous and heavy. Weight wise, you would be much better off with a warmer bag. If you can't afford to get a new bag, throwing on a ton of layers will work, if you have the extra space in your pack. I have been there and done that, but the temperature distance you are suggesting is massive. It would be very hard to tell how much you need and underestimating could be very painful.
I have the lamina 35 and it's definitley a little optimistic. I need long underwear, thick wool socks, a good warm hat, and a a couple light wool sweaters to be comfortable at freezing. If I am going to push it, I will usually blast a fire all night. It is very effective but probably too much work for most.
