Nope. A .410 is a gun for sport- if you're trying to actually survive, almost
anything is better. More powerful rounds take up less space. For small game, rimfire rounds are considerably more compact, but have longer range. .410s are toys. Even that load you linked specified it's for
close-range defense. If you're going through the trouble of packing a shotgun or rifle, why would you limit yourself to something that won't even extend as far as a decent handgun can effectively shoot?
A single-shot .357 rifle would be much better- heck, one could even get a Contender rifle, put an M4 adapter on it, and get a sliding stock little carbine that would shoot .38 or .357. It could be a little pricier than some other options, but could be extremely compact, and with good ammo, would be very accurate.
A cheaper way to go would be to buy a
H&R .357 Carbine, and have a gunsmith shorten the barrel to 17", and the stock to 12.5" LOP- or just buy the very short
youth stock. Then you'll have a compact, lightweight carbine that can shoot .38 wadcutters for harvesting small game with low report and minimal meat damage, and move all the way up to full-bore .357 for rifle-sized game. ATI also makes an M4-style sliding stock, but I'd prefer Choate.
Though not as useful for outright
defense, any of the "pocket rifles" like the XP-100 and T/C Contender or Encore, in the right caliber, could take game out to 200 yards or further. These would be even easier to pack than any longarm except perhaps the Sub-2000.
