pic32mz vddio at 2.5v, can I run usb with Vddio at say 2.4V

After looking through the usb standard, which states that voltages on d+ and d- can go up to 3.6v, and after reading the manual of the pic32MZ series of processor which states that d+ and d- lines can handle up to Vusb3vb3+.3v, it is obvious that in order to handle d+ and d- at 3.6v, Vusb3v3 must be 3.3v.  As I am communicating with other peripherials which cannot handle much over 2.5v, I was desiring to run vddio at around 2.4v.  Can I run Vusb3v3 at 3.3V when Vddio is running only 2.4v?  I have spent hours looking through the manual yet haven't seen a clear answer to this question yet, nor is there one that I have found on the forums yet.
