I think it'll work but be less productive and need more watering.
I'd be very interested to hear how your experiment goes!

When the spears get small and spindly, you need to let the plant just do it's thing. It becomes a big, tangled mess -- ferny branches going all over the place. It's not a space-efficient plant, but rather, it consumes a lot of garden space as the asparagus fronds flop over and try to maximize exposure to the sun so it can create an energy reserve for next season. So if you had a place to transport those planting boxes/barrels/containers for the majority of the year when the plant isn't bearing, yeah, a greenhouse might be a solution. But don't count on picking a big bunch of asparagus and having a nice amount for a meal. You'll get 2 spears today, none tomorrow, 1 spear the next day . . . There are so many more efficient veggies to grow in a greenhouse than big, tangly asparagus plants. For the small amount of asparagus you'll actually get for all your effort, I'd spend $5 at Costco and buy a bunch there.
