I am not sure what type of lino you have, I know there were problems with some types cracking but yours seems a little too recent for that to be the case. If it is only buckling maybe you can inject glue and weigh it down until it sets.
If you are lucky enough to find the matching lino, there are people who can do a flawless repair by cutting out and gluing in a new section.
Finally, while the lino does run under the counters and cabinetry, I see no reason to remove cabinets to replace it. The only reason it runs under is because it is much easier to put it on before they build the interior.
Best you can do is to find a dedicated lino repair expert. DO NOT count on your dealer.
