I don't think it is possible currently.
To a degree you might be able to work around it by creating additional 
labels that combine the existing ones e.g. "L1", "L2", "L1-L2".

I was pondering trying to implement test filtering based on the 
condition evaluator CMake uses for if()/while() at some point 
(cmConditionEvaluator.cxx).
e.g. --run-tests-if "L1 IN_LIST TEST_LABELS AND L2 IN_LIST TEST_LABELS"
