There's no fixed process name in Linux that cannot be easily faked: 

Use process name -- every process can change that by writing to its own
environment.
Use comm name -- there's a prctl to change that and there can be collisions
Use path name of binary -- breaks with chroot and name spaces. Also existing
binaries can be subverted.
Use inode of binary -- can be faked with fuse and breaks when the binaries
is copied ...
Use dev, inode -- breaks when copying binary and when running on network
file systems without a device node
