Assuming you have all maintenance applied to ENT COB 4.2, there should be no problem doing a BUILDMCS and receiving/applying into your z/os V2.3 environment. There is no "LE V4.2". LE follows the z/OS level. I did exactly that, but put it into its own target/dlib zones and target/dist libraries, as we are currently migrating to ENT COB V6.2, which is in my existing z/os target zone, and different datasets. Eventually, the ENT COB 4.2 libraries will go away.
As for levels of LE, it's not an issue like it used to be with the separate COBOL runtimes. The only reminder is that occasionally, the compiler introduces new features that require new runtime support(LE) PTF's. If you operate in a multi-system environment, then you must roll-out the LE PTF's for that runtime support to all systems BEFORE you introduce the new COBOL feature, or you will definitely run into problems. These changes are always called out as HOLD ACTIONs when applying maintenance. Quite often I'll have to add a USER HOLD to the compiler PTF, while working on maintenance cycle to allow the LE PTF to propagate to all systems in the environment first. The same is true when changing the ARCH level in the Cobol options. Make sure ALL of your systems are migrated to the new hardware before changing the ARCH value used at compilation time.
