Yes, you can remove the wire from your bra.
If you have an underwire bra that is uncomfortable, you can remove the underwire entirely and continue to wear the bra. This process effectively converts it into a wireless bra that you will wear. As the reference states, there's no benefit in keeping an uncomfortable bra unused when it can be modified to be wearable.
Removing the wire is often done to make a bra more comfortable or to salvage a bra where the wire has poked through. While the original support structure will change, the bra can still offer some level of support and coverage as a wireless garment.
