No.
There may be some niche applications and specific businesses which use APL, but I don't think there are any fields where it's commonly used. As you've noticed, the Wikipedia article is really just cherry-picking specific instances where it has been used, some of which are 30+ years old.
That's not a question one is able to answer objectively in this world full of closed source software.
Large parts of SimCorp (https://en.wikipedia.org/wiki/SimCorp) Dimension, a suite of software for investment management used by a fair number of European banks and pensions funds, are written in APL. That said, Dyalog exists, and SimCorp does not play any grand role in its existence. So there must be others out there. The mere existence of APL keyboards is proof that there is a market for these things.
Indeed, quite frightening at times seeing the value of firms using Dyalog APL.
