The specific limits are in the Operating Specifications for each 135
operator but they will be the same as the general rules that you cited
(60-70%). The rule is intended to force conservatism on choosing landing
runways. These rules are covered ad nauseam on the ATP written test...to
the point that I still remember them:-).

Part 135 spells out what percentage of the runway can be used for landing
and also requires using 150% of any tailwind for the landing distance
calculation.

Can you give a more specific pointer into the regulations? FAR
135.385/387 seem to forbid *take-offs* unless landings can be
*expected* to use = 60% or 70% of the runway. That does not seem to
require *actually landing* that way, only that this be possible. The
rule appears really intended to require limiting the aircraft load.
