If you mean "will it be OK this weekend, I'm dropping it off on Tuesday", then yes, almost certainly.Can I still drive in this until I can get it to the shop?
As you've noticed, it affects your steering and will contribute to tire wear. Even though you could probably get away with driving it like that for quite a while, you'll eventually chew up the tires, too.
Replace the whole control arm. If it were me and I planned to keep the car, I'd do the whole front suspension on both sides while you're at it. At 10 years, you got your money's worth, even if your mileage is low. Bite the bullet now, do one alignment, and drive it another 10.
