How large of a "hole" applies to 400.8(2) not permitting a cord to run through a hole in the wall?

What I would like to do is have what could be described as a large hole, opening or small doorway in a wall between a kitchen and a well ventilated utility room. The size of this hole would be just large enough to push a refrigerator through. The intention is for the rear of the refrigerator to expel heat into this utility room, instead of into the kitchen. The refrigerator may be placed near the hole, or just in the hole, or possibly pushed part way through. A removable molding or other assembly would be fitted around the refrigerator to conceal the existence of the hole, giving a built-in appearance. There would be no portion of a wall directly behind the refrigerator except for the wall on the other side of the utility room itself.

I would like to have the receptacle for this refrigerator be located in the utility room. When standing inside the utility room facing the rear of the refrigerator, the outlet for the refrigerator would be on the wall just next to the opening the entire rear of the refrigerator can be seen at.

So does an opening 36 inches wide and 72 inches high constitute a hole for the purpose of 400.8(2)?

I might want to do this for more than just the refrigerator, too.
