Zion is very likely the name of a chapel, though after looking at the National Index of Parish Registers and several old maps I haven't been able to find one of that name, nor any kind of cemetery, in Holme Lane, Tong. Is it possible that Holme Lane is the address of the deceased or whoever arranged the burial, rather than the cemetery?
The nearest Zion chapels that I've been able to find (though there might be more) are Methodist New Connection ones in Adwalton and Pudsey, and an Independent/Congregational in Wibsey.
For researching in this area you might find help from a cluster of related sites:
