Charlotte vs Charlotte metro -- two separate things.
If you're not from Charlotte or familiar with the area, then you're probably thinking the city. I would not say Weddington is in Charlotte.
If you're from Charlotte or familiar with the area, then you're probably at least a bit familiar with Charlotte metro. I would say Weddington is definitely part of the Charlotte metro. Geographically, it's a pretty large area.
