yes you can design it provided that you atleast have min reinf! but should be less than maximum

point to note here that max reinf ratios changes for single and doubly reinf beams

In addition when you take reduced moment capacity based on phi factor...note that its not always equal to 0.9 it can be 0.85, 0.87 etc..depending upon strain compatibility according to ACI....from compression cold to tension controlled section!

read any NILSON concrete design book 14th edition beam chapter....

Ofcourse there is minimum reinforcement ratio for every concrete member....you cannot put less than that..but you have to be sure that its also satisfying strength design! and serviceability too!
