It is possible, you can create a boolean field as part of your ViewModel which is set to false if there are no children. And you can then configure your TreeView model to use that field for the HasChildren option.
e.g.
@(Html.Kendo()
.TreeView()
.Name("tv")
.DataSource(ds=>ds.Model(m=>
m.HasChildren("theNameOfTheField")))
)
