You can email Google a complaint.
The last time I complained about a search result, it was repaired by the time I could even refresh my search to check if they fixed it.
I am looking at one map that has “Dump Tower” and “Trump Tower” on the same building.
I just sent a complaint (using the “Feedback” function on the bottom of the page) and highlighted the pertinent section of the map.
From the behavior of the “Dump Tower” label when I tried to click on it to make the complaint, it looks like it was a user addition, and not an actual Google Maps label.
In addition, when one overs the mouse over other stores/buildings/establishments, a popup appears with the name and a couple of details. Not so for Trump Tower.
