Yes:

+/* Get innermost frame of first thread of core file COREFILE.  Returns NULL on
+   failure.  */
+extern Dwfl_Frame_State *dwfl_frame_state_core (Dwfl *dwfl,
+						const char *corefile);
Tested on core files generated in tests/run-backtrace.sh.

For non-x86* there are testcases (also via tests/run-backtrace.sh):
