Surely if it's only a path it's not going to be very deep - a few
inches

Indeed.

Rather than smacking it with a sledge, consider hiring a concrete
saw
and cutting it into bits small enough to be levered up.

It is suprising how delicate you can be with a Kango if you don't go
hammer and tongs at it. A few years bask I managed to remove a cast
block of rough concrete 18" cube that had been placed totally encasing
a 4" salt glazed drain. The concrete had been placed by the previous
twit owner who 'repaired' a crack by tying lino round the pipe and
encasing it. As far as I could tell the only crack in the pipe was the
original one.

I smashed up a concrete path in my garden with surprisingly little
effort and no chance of collateral damage. The trick is to find ( or
make ) a weak spot and then lever the concrete slab just a fraction of
an inch clear of the ground so that there's a small air gap underneath
it.

A small whack with a club hammer will easily break up the unsupported
part and then you can attack the next part. I did the job very much
faster than I anticipated.
