It is, although you still have to test to be sure.  Providing tested binaries for PyObjC is on my wishlist, and has been for quite some time.  With those binaries it would be a trivial task.

In general it should be possible to build an application needs to be deployed on on older OSX release by setting the deployment target appropriately[1] when building the C code. The hard part is making sure that the build process doesn’t pick up unwanted dependencies, especially when using autoconf. PyObjC, and Python itself, should be safe in that regard.

[1] Ignoring PPC, Apple’s toolchain doesn’t support that with recent enough releases of Xcode.
