No. The eQEP pins are only available on a few specific pins of the CPU. Refer to the pinmux spreadsheet I referenced earlier:
https://github.com/cdsteinkuehler/beaglebone-black-pinmux/blob/hal_pru_generic/pinmux.ods You *HAVE* to use the pins that have the eQEP*A and eQEP*B (where * is a number from 0 to 2) available as a pinmux option.
