Answer:
Yes, 100 %. 

Evidence:
Chris gets in a difficult situation. He steps on an anti-personnel mine. One move, and... Sam don't hesitate one second. He is endangering his own life, but removes the Mine. See: "Phoenix"/"Phoenix aus der Asche", 03.04.99. 

Alone and without help Sam and the hurt Chris have to survive in Africa. In the end, Sam actually carries his completely exhausted Partner. See: "Tusk Force"/"Die große Jagd", 10.04.99 
 

Comment:
Ah. Give me a nice emergency, and I can tell you... Here is the suave Sam Curtis, the "courtier"* discussing french cuisine. Emergency comes: Chris steps on a mine. What is Sam doing? Discussing the situation in a stylish way? Doing something elegant? (Getting nervous? Going away? - There are always excuses, when you don't want to do something.) No. He switches instantaneous in another mode, which seems to be there in deeper spaces. Learned somewhere, where Life is simple. You are hungry: you eat. You are thirsty: you drink. Someone you know is in an emergency: you help. This someone is your partner and friend: you help, no matter what it costs. And Sam knows this code by heart. No insecurity about what he has to do. His crude jokes about Chris's situation being just "Galgenhumor", because 40 seconds later he will remove the mine which endangers him as much as his partner... 

Okay, lets face it: It seems not entirely professional, to carry your partner on your back through Africa. I mean: Chris seems to have about the same weight as Sam. How far can you carry your own weight? 1 km? 2 km? When comes exhaustion and you are both a "Fressen für die Geier"? But. (Of course, here comes the "but" now!) If you would be the hurt one with the broken leg: Would you really like to lie somewhere alone because the only person you can rely on is "reasonable" and "professionable" (and damnable**) going away to seek help? And is "reasoning" not again only an excuse for running away? There are always at least two ways... And here again there is this strange streak in Sam: He will not give up, and when Chris can't walk anymore, he will carry him and does carry him. He don't have to think about it, he just does it. "Vernunft" hin oder her.

Hm. This got a little bit long. But if you were ever in an emergency, you will understand, why I explored this more thoroughly. (It is astonishing, how "friends" tend to vanish in a difficult situation. Make a test! Ask one for example to lend you his car, because you have an ill mother/child/husband - and yours broke down...)

** Really, I still hate Ralph Fiennes for letting alone Kristina Scott-Thomas in "The English Patient". Yeah, nice picture, how he carries her dead body (after letting her die alone in a pitch-dark cave). Would have been even a nicer picture, if she would still have been alive! (Give me one Sam Curtis for 10 bloody Count Almassys or what his silly name was.) Suits him right, what happens to him later...
