I don't think so. Not because of weight but because of space. Good question though. I just don't think they could pack 30 Iridium satellites into the payload fairing. Which begs the question of how many they could fit in if they needed to?
Which is an issue for FH. That is where a rocket like New Glenn and Arianne Rocket come in. Those rockets have a larger fairing to fit larger payloads. New Glenn dropped its smaller fairing for the larger fairing because there was more demand for the larger fairing. I'm almost certain that SpaceX cannot increase the size of their fairing without a major redesign that the company is unwilling to do.
Back to Iridium. They have 40 satellites up and only have 35 more to go. All four of those launches should be completed by the end of the year. The second launch around April this year will be shared with a NASA payload.
Also Iridium is planned to be 66 satellites in 6 orbital planes, so can't have too many in one launch.
