Sorry - I was sleeping, hence the delay on my part.
Simply crop the image with imcrop(), then call imclearborder(), then pad with padarray():
margin = 50; % Whatever
croppedImage = imcrop(binaryImage, [margin, margin, columns - 2 * margin, rows - 2 * margin]);
binaryImage = imclearborder(croppedImage);
binaryImage = logical(padarray(binaryImage, margin));

No. It will remove any object, no matter what size, if it enters the margin. If you want size based filtering, see bwareafilt() or bwareaopen().
