You could make field B a function field and 'mirror' field A, if both fields should show exactly the same.

def _get_A(self, cr, uid, ids, field_name, arg, context=None):
    for obj in self.browse(cr, uid, ids, context=context):
        res[obj.id] = obj.field_A
    return res

columns = {
    'field_A': fields.many2one(.......),
    'field_B': fields.function(_get_A, type="many2one", obj='field_a_model', method=True, string='Field B Name'),
