Unlikely. There would have had to have been a Soyuz almost ready to go that could be used for the purpose, and there wasn't. I'm also not sure that a Soyuz could have been launched from Baikonur into the orbital plane that Columbia was flying in; they commonly launch into the ISS' orbital plane, and we already know Columbia couldn't have gotten there. And, even if you could get a Soyuz there in time, Columbia wasn't equipped for retrieving supplies from another spacecraft. It wasn't carrying a RMS robot arm, for instance, nor did they have any SAFER jetpacks for their pressure suits. Getting supplies out of another spacecraft, even one nearby, without either of those would be tricky at best...maybe too tricky for a crew already possibly suffering from partial CO2 poisoning.
