Given that the US government routinely plans for individual hulls to be in service in excess of fifty years (e.g. the Nimitz and Ford class aircraft carriers), and that the 1950s-era B-52 bombers are expected to remain in service until 2040 (a service lifetime of over 85 years), I do not find a 100-year lifespan so unbelievable, assuming that the systems get regularly upgrades (e.g. the 2409 Excelsiors will have post-TNG-era warp cores, sensors, phasers, etc.).
