As Mah's sisters believed that she was stillborn, that definetly sugests that they can die, if they don't sustain enough power. Jagex have stated in the past that they cannot die, but I think that means by any normal cause of death, even when weakened, and simply enter that comatose state to remain indestructable. But without Anima, that would fail, and so would assume so would their main safegard against mortality. However, there could be other ways for the Elder Gods to sustain their imortality... such as ripping the power they gave to create back into themselves, much like how the Ritual of Rejuvination worked with the Mahjarrat before Zaros repurposed it.
