Well, actually there seem to be three versions:
The manual says that the argument to remove-view-from-window
is a view.
The built-in documentation (c-x c-d) says that the arguments
are a view and a window.
If you inspect the function the inspector window says that its
arglist is nil.
The manual appears to be correct - the function works as one would
expect from its description if you give it a view as an argument.

Well, remove-view-from-window seems to work OK at doing that. Here's
some test code to demonstrate that:
(defclass special-view (view) ())
(defmethod view-draw-contents ((s-v special-view))
(frame-oval s-v #@(0 0) #@(100 100))) ;so we can see when the view
(defmethod install-view-in-window ((s-v special-view) window)
(set-back-color window *blue-color*)
(call-next-method s-v window))
(defmethod remove-view-from-window ((s-v special-view))
(set-back-color (view-container s-v) *red-color*)
(setf the-view (make-instance 'special-view))
(setf the-window (make-instance 'window :color-p t))
;;Then try the following in succession:
(add-subviews the-window the-view)
(remove-subviews the-window the-view)
