The Japanese royal family is the longest continuous royal bloodline on record. Oral records say its 2600 years old while archives exist from the 6th century.
So, a family of weavers going back hundreds of years, now switching to carbon fibre production under the direction of an unrelated (adopted) heir can said in Japan to still be the same company if that carbon fiber is woven.
But also, sometimes "core competency" is re-interpreted. Perhaps the original core competency was as dyers, which morphed into weaving at some point, and might eventuall change to "anything involving carbon fibre"…
