Does the Motion 35XTi work with the AVR-X2900H?

Yes, with one setting change. The Motion 35XTi is 4 Ω: set the receiver to 4 Ω in its speaker setup.

Will the AVR-X2900H damage the Motion 35XTi?

Not once it is set up for it: the AVR-X2900H is rated for a 4 Ω speaker with its speaker impedance set to 4 Ω.

Is the AVR-X2900H powerful enough for the Motion 35XTi?

More than you need. From a seat 2 m away, loud 95 dB movie peaks take about 16 W per speaker, and the AVR-X2900H is rated 95 W per channel. Cinema reference level, 105 dB peaks, takes about 160 W.
