Thunder Charge

Tier: 3
Prerequisite: Strength 50
The character charges into combat using his body as an
additional weapon to push foes away or to the ground.
Driven by rage and momentum, the impact of such a charge
can knock a foe flying or bring them their knees. When the
character makes a Charge Action he can barrel through foes
to get to his target. Make an Opposed Strength Test between
the character and each foe in his way (i.e., each foe his charge
would take him past or through). Those that fail are knocked
to the ground. Once the character has tested to knock down
those in his way, he may complete his Charge and make his
attacks against his intended target.

What happens if  the Foe wins the Opposed Strength Test?

Does the charging character make his attack on the Foe who stopped him or does his charge just stop?

I suppose it would be up to GM, depending on circumstance. For instance, a Space Marine charges through a group of humans, anyone that passes the strength test manages to stay on their feet, but that is all. A suitably heavy enemy, like another Space Marine in Terminator armor or a large daemon, might totally stop the charging character. You might also say that larger targets are still at least pushed out of the way, rather than stopping the character. This would be to represent the fact that the character takes any obstacle into account on his charge and will try to aim for weak or unbalanced spots, rather than just going head on.

When I used T.C. our GM had it that if my opponent won the Strength Test (As unlikely as it would be verses a Khorne Marked Space Marine) they would get an attack of oppertunity as my character rushed by them.

Those that fail are knocked to the ground…

That could include the charging character if he fails the opposed Strength test. Needless to say, if you go with this interpretation, you really only want to use this against smaller and weaker foes.
