No.
It could be, as the interpreter is a pluggable component. You can configure the interpreter to be used in the INI file.
There is an example config which uses a non-g-code interpreter:
github.com/LinuxCNC/linuxcnc/blob/master...sim/axis/canterp.ini
This line:
INTERPRETER = libcanterp.so
means that it uses input files that look like this:
github.com/LinuxCNC/linuxcnc/blob/master.../canterp_example.can
So: No, linuxcnc only currently supports G-code and the (example) .can as input files. But if someone wrote an interpreter, it could use any other input file type.

but you could apparently use this to convert to gcode:
wiki.linuxcnc.org/cgi-bin/wiki.pl?AptProgrammingForEMC

quick answer is YES .
APT 360 & postp ... available from sourceforge is quite easy to install and run once you have a feel for APT.
I have installed it on even a Raspberry Pi-Zero.
There is an EMC post-processor that tailors the code specifically for the linux cnc interpreter.
I have done quite a bit of APT programming and would be glad to assist if required.
All the best
Denis
PS I have a pretty sweet deep hole drill macro that has saved many dollars in tooling if anyone is interested.

I think that going through G-code might be inefficient, though.
The LinuxCNC G-code interpreter converts G-code to canonical commands:
github.com/LinuxCNC/linuxcnc/blob/master...l_intf/canon.hh#L199
And the vast majority of what is produced is a sting of straight-traverse, arc_feed and straight_feed commands.
Modifying the APT processor to go straight to these rather than via G-code might be a more satisfactory solution.

I believe that postp could be hacked to provide something like that canon link.
Do you have an actual program file in that format I could look at??

Who are you asking, and which format?

Sorry,
That was for you Andy.
I was referring to the canon format.

It doesn't really exist as a file. It is the stuff that gets sent from the interpreter to the motion system in LinuxCNC.
For example, here is what happens when LinuxCNC interprets a G1 command:
github.com/LinuxCNC/linuxcnc/blob/master...erp_convert.cc#L4522
As a demonstration of pluggable interpreters there is a demonstration interpreter called "canterp" that converts files like this to canonical actions: github.com/LinuxCNC/linuxcnc/blob/master.../canterp_example.can
But that shouldn't be created by an APT interpreter, there should not be an intermediate format.
But: Is there really a requirement for this? It is probably a lot of work. Who would use it?
A similar effort might create a STEP-NC interpreter, which might be more useful (or not)
