*** completely re - edited having reread your question again and having read FDs excellent post below: There is no minimum temp on the chart you mention because it is not a "VNAV procedure" , IMHO the chart/minima is drawn on the basis of you using LNAV and VS or FPA having applied the appropriate corrections i.e. It is what FD describes as a 2D approach. Can you substitute VNAV? What does your ops manual say (we can in certain circumstances)?
On a more general point if no minimum temp is published for a "VNAV procedure" our ops manual says, to paraphrase "In the case of an RNAV approach where no minimum temperature is published....... pilots should assume a minimum temperature of ISA -25 for the use...of VNAV."
FWIW We have uncompensated baro VNAV and are not allowed to alter RNAV altitudes in the FMC.
