Depending on how you look at it some platforms are already running Linux.

QFX5100 runs a Linux KVM hypervisor with the traditional FreeBSD based Junos running as a guest. Same with the new x86 based SRX (SRX1500). There are more moving to this model.

The x86 based SRX is the most interesting with the forwarding daemons running on the hypervisor OS and the Junos based VM is just for management and protocols. It's not that hard to see that management and protocols can be easily ported.

There are more details that are locked behind an NDA.
