It doesn't "stack" with corrosive projection because they do different things.

Corosive Projection reduces the armor rating of all enemies in a mission upon loading into the mission. Corroding Barrage applies corrosive procs to enemies that are hit.

So technically you can use both together but they don't "stack" the way two same effects might stack. They do different things and work together. By using corrosive projection you reduce enemy armor so corrosive procs have less armor to remove (making enemies die faster).
