This is not correct. In fact, LCDM can't even explain the Bullet Cluster [1]. The evidence is not so favourable to LCDM over MOND [2] when taken as a whole.

More recent observations on wide binary stars disfavour MOND more strongly, but the classic reasons you cite are not valid reasons.

Edit: See for instance what Milgrom said about the Bullet Cluster back in 2006:
