It is perfectly safe to use a good handheld for en route in most
circumstances, provided the antenna is located correctly, and so forth.
En route RAIM is a very loose spec, compared to approach RAIM.
But, the issue here is legality.
Then, there is the question of having a current database, more for safety
than legality in this case.
Legality isn't an issue either. Since use of a handheld GPS during IFR
enroute flight in US controlled airspace does not by itself violate any FAR
it is perfectly legal.
