Out kitchen has laminated Chipboard worktops. (My wife'e eysight wasn't
compatable with the granite ones)
The butted joints were probably not sealed as well as they should and some
slight swelling is becoming noticable.
I was wondering if a solution could be to route a shallow groove and then
fill it with an epoxy type filler.

Perhaps route, but brush silicone sealer well into the groove then top
off conventionally whilst still unset, for a finished seal?
Tape along both edges will ensure a neat finish and remove when wet.
I sealed a hob cutout once in chipboard by smearing silicone around the
cut face. Seemed to work and the chipboard is so rough that the silicon
seems to really bind.

I think any groove filled even with a matching filler will stand out like a sore thumb
especially if there is any pattern in the top surface. Your best option of keeping the
existing work top is to separate the two pieces and try to scrape out any expanded
chipboard and gently pressing the top surface back into position before filling any gaps
Even doing that I think the success rate will be very low as melamine top surfaces are
quite hard and brittle and will tend to crack and chip very easily.
If going the routing route, then I would see if you can get a matching
strip of laminate for the worktop (most of the sheds do them so you can
cover cut edges etc). Then using a made up jig and guide bush, you can
route a slot wide enough to cover the join. Change the bush, and route
the exact matching infil bit. Paint the exposed chip with SBR to seal
it. Finally glue in the patch with impact adhesive.
