The answer is dependent upon the catalog number of the load center. Some load centers accept tandem breakers in all positions (ie: QO12040M200 is a 20 space - 40 circuit maximum load center that will accept tandems in all 20 spaces). Some load centers accept tandem breakers in specific spaces only (ie: QO13040M200). In this example, the QO13040M200 has 30 spaces with 40 circuits maximum, meaning that it will only accept up to ten one-pole tandem breakers. The spaces that accept the tandems will be the lowest ten spaces of the interior.
