You're joking, right?

ATC can give you any clearance they want. You don't have to accept it,
and can't if you don't have the equipment to fly it (i.e. route requires
DME and you don't have DME). But, you'd look pretty stupid saying,
"unable airways, negative chart".


No, you don't have to accept it, but there may be no other alternative
available.
