Found this small tree on my walk, seemed to be growing fruits but the leaves are smooth whereas every cherry I've seen has serrated edges to the leaves
That's Alder Buckthorn, as the leaves are alternate along the stem. Ordinary buckthorn (also known as purging buckthorn ) has leaves in opposite pairs along the stem. Buckthorn also has very finely toothed leaves, whereas alder buckthorn is untoothed.
What you call purging buckthorn is that what I'm familiar with as sea buckthorn ? Or is that different all together

Buckthorn Family (Rhamnaceae):
Buckthorn (aka purging buckthorn) - Rhamnus catharticus (isn't that a great specific name? )
Alder buckthorn - Frangula alnus
Oleaster Family (Elaeagnaceae):
Sea buckthorn - Hippophae rhamnoides
So sea buckthorn is not especially closely related to the other buckthorns, at least according to my reference book.
