Lovely photos Gardening Grandma. The tree does look a fine specimen but I can understand why you might think it's not in the right place !! I'm afraid I can't place the identity of the tree but the leaves look familiar !!!
Sorry I cannot be more helpful but I'm sure others will know what it is from the photos.
Having looked at another query in this forum, I'm now wondering whether this is a goat willow and I have simple missed the catkins, either because they are small or because I just haven't looked at the right time of year. Until this year, it was behind the greenhouse. I think I have spotted a similar small tree in a nearby garden. If so, I would feel safe in leaving it there.
