Is it wise to leave this tree where it is?
This is a volunteer. It is in our front yard to the east of the house. We have a ~40 ft maple tree on the boulevard (southeast, about 20-25 feet away from this tree) and a brand new espresso Kentucky coffee tree (due south, about 20 feet away from this tree). We were told this was a Black Walnut and were told to get rid of it because it would get too big. Our priorities are the maple and espresso.

Your tree is not a walnut but a winged euonymus. It is considered invasive. I would remove it. Here is a link to read more about it. https://www.minnesotawildflowers.info/shrub/winged-burning-bush
