I think so. There would be two caveats, though :
1) The ROM would have ot have the right pinout (although I am pretty sure
IBM used a standard one).
2) The ROM had better not look like a valid BIOS extension ROM (i.e. have
the right header and checksum) if you don't want it to be executed at
boot-up.

...there was room for 48K of ROMs, with
40K being used (IBM 5150)
therefore anything you plug into those extra rom
sockets would allow you to access them and create a
"hex dump" if that's the right term, and save it to
disk. ISTR Intel having some sort of hex format for
rom images.
