Only by using the callbacks to check and enforce it.

function CountSelectedStates(hobject, event, handles)
% Get states of all the checkboxes.
selectedStates(1) = get(handles.checkbox1, 'value');
selectedStates(2) = get(handles.checkbox2, 'value');
selectedStates(3) = get(handles.checkbox3, 'value');
selectedStates(4) = get(handles.checkbox4, 'value');
% Count how many are checked right now.
totalNumberSelected = sum(selectedStates);
% Check which one was just toggled
if hObjects = handles.checkbox1
% If you want to implement Walter's suggestion.
% They just clicked on checkbox 1.
% more code.....
end
if totalNumberSelected >= 3
% Clear states of all the checkboxes, like you wanted.
selectedStates(1) = get(handles.checkbox1, 'value');
selectedStates(2) = get(handles.checkbox2, 'value');
selectedStates(3) = get(handles.checkbox3, 'value');
selectedStates(4) = get(handles.checkbox4, 'value');
% Keep the one they clicked on checked.
set(hObject, 'value', 'on');
end
and so on.

Some small corrections to the above:
if hobject == handles.checkbox1
and to clear the check boxes, do not get() the values, instead
set(handles.checkbox1, 'value', 0);
