Sure. If you don't want to spring for the magnetic plates, of course.
Once you can do 20 reps with 10lb dumbbells, I suspect you'll be able
to get at least a few reps out with 15s, right?
Otoh, if you're only curling between 10 and 15 pounds then why not
simply do your curls at home?
Buy two gallon jugs of water (about 16 pounds) for one-armed curls.
(Four jugs for two-arm curls, naturally.) Pour out a portion of the
one jug and then hook your hand through the two grips. Curl away with
from anywhere between eight and 16 pounds depending on how much water
you've poured away. (Take your own weight and then stand on your
bathroom scales while holding the jugs to determine how much they
weigh. Subtract, right?)

An Olympic bar? A 45-pounder?

Each time you reach ten reps then increase the weight a bit. Work with
that until you hit ten reps again. Simple.
Best of luck.
