Ted Kazinski was concerned that high energy particle physics would create a blackhole large enough to become self sustaining. If I remember correctly, high energy physics creates tiny black holes during particle collisions, but they "evaporate" faster than they can absorb mass.
So to answer your question with my limited understanding, yes, there's a lower limit to stable black holes. Beyond the critical mass, they simply evaporate in a matter of seconds.
