That should be OK.

GnuCash has a collection of "features" that reflect changes to the datafile when a newer version makes changes that aren't backwards compatible. Once a feature is set older versions of GnuCash that don't support that feature will refuse to open the book. The features are enumerated in https://github.com/Gnucash/gnucash/blob/stable/libgnucash/engine/gnc-features.cpp and the latest requirement is GnuCash 4.3 so as of now that and all later versions of GnuCash are fully data-compatible.
