In the good old days it was perfectly possible to get yourself truly stranded, with no possibility of getting out of the system other than self-destruction (and that is, in fact, how the famous Anaconda Graveyard came to be.)
Fleet carriers changed this radically: Now there is no system remote enough you could jump into with a ship that a fleet carrier cannot reach. Thus, there's always the possibility of someone rescuing you with a fleet carrier.
But the question remains: Is it still possible to strand yourself completely, with literally no way of getting out nor getting rescued (ie. the only possibility is literally just self-destructing)?
Here's one way I think might work: Build yourself a ship with a maximum jump range smaller than 5.2 Ly, go close to HIP 22460, and use your last jumponium material to jump there.
The reason why I think you will be truly stranded is that HIP 22460 is uninhabited and permit-locked (and you have the permit for it), which means there's no station there where you could help rescue yourself, and nobody can come to your rescue with a fleet carrier. (The reason for the 5.2 Ly is that that's the distance to the closest system from there.)
There's one possible caveat that I can think of, though: If there's mineable jumponium in the system itself, someone could come with mining equipment and mine it for you, allowing you to FSD inject. I haven't checked if there is all the jumponium materials necessary in the system.
If there is, here's plan B: Build a ship with a max jump range smaller than 2.4 Ly, supercharge at Jackson's Llighthouse, use a fleet carrier to go to the system closest to HIP 22460, and then jump there. Now even jumponium will not help you to get out.
(As far as I know, HIP 22460 is the only uninhabited permit-locked system for which you can get the permit. Thus, it's the only one for which this plan is possible.)
