You are correct. It is fine to exceed Vcc with either
input.

Vicmr is the absolute maximum voltage range, beyond which the device
will be damaged. The operational common mode range is given in the
"Electrical Characteristics" section of the data ***, and is the
input common mode voltage range over which operation is guaranteed.
This range is given in terms of Vcc. Unfortunately, the LM339 data
*** does not give the Common Mode rejection ratio (CMRR), so you can
not determine how much the input offset voltage will change over this
common mode input range.
