"Depend on if" means "depend on whether"?

Can I replace “depend on whether” below with “depend on if”? I ask because “whether” can be replaced with “if” some times. ‘I’ll see whether she’s at home’ same as I’ll see if she’s at home.

Second language learners’ divergence from target language pragmatic norms | Studies in Second Language Learning and Teaching. Maria Pia Gomez-Laich.

Although the importance of explicit teaching of pragmatics is well recognized in the literature, learning norms and rules of pragmatics largely depends on learners’ subjectivity. Learners’ convergence or divergence from the L2 pragmatic norms, both consciously and out of awareness, sometimes depends on whether these norms fit their image of self and their L1 cultural identity. Since identity-related conflict can have significant consequences for the acquisition of second language pragmatics, failing to consider the centrality of learners’ identities will produce an inadequate understanding of SLA.

That is, the L1 appears to influence pronunciation in the dominant L2, but not the other way around. Perception experiments with a larger sample of Greek–English bilinguals (Antoniou et al., 2012, p. 592) reveal a still more complex pattern of dominance relationships, one that depends on whether the task is categorization or discrimination of voicing: “The results suggest that a bilingual is a single (dominant-language) listener with respect to discrimination, but behaves more like a monolingual of the activated language with respect to discrimination judgments.”

whether a language allows null subject or not

• depends on whether INFL is proper governor (GB)

• depends on morphological uniformity (B)

• depends on whether affixes are generated in the syntax or in the lexicon (MP). See Katamba (1993:56,158-59).
