Yes :-). It's not pretty and you've lost all the symbol info, but you can
disassemble everything (including data!). e.g.
echo > foo.c
arm-elf-gcc -c -o foo.o foo.c
arm-elf-objcopy --remove-section=.text foo.o
arm-elf-objcopy --add-section=.text=thebinfile foo.o
arm-elf-objcopy --set-section-flags=.text=alloc,load,code,contents,readonly
foo.o
arm-elf-objdump -d foo.o
