Well, Linux native and Linux Swap partition types are independent from the DASD layout. Both, cdl and ldl DASDs could have Linux native partitions. The DASD layout tells you how many partitions are possible (ldl - one, cdl - up to three). The partition type (e.g. 0x82 for Linux native) tells you, what kind of partition you have. One big difference between cdl and ldl is the volume label, cdl has VOL1 and ldl uses LNX1. But the easiest way to find out is dasdview:
